Novel wind power main bearing sealing structure

Abstract

The invention discloses a novel wind power main bearing sealing structure, and relates to the technical field of wind power bearing protection. In order to solve the problems that in the prior art, acheck ring used for sealing and arranged on a wind power main bearing is inconvenient to mount and disassemble, mass production is not convenient and the production cost cannot be reduced, the structure comprises a bearing outer ring, a bearing inner ring and a plurality of balls. The bearing inner ring is movably sleeved with the bearing outer ring, and the balls are arranged between the bearingouter ring and the bearing inner ring. The outer wall of the front side of the bearing outer ring and the outer wall of the back side of the bearing outer ring are each provided with a first mountingblock in a welding mode, and movable plates are rotationally connected with the sides, away from the bearing outer ring, of the first mounting blocks. First limiting mechanisms are arranged between the movable plates and the first mounting blocks. By means of the structure, a sealing plate can be quickly assembled and disassembled conveniently. Besides, the whole device is simple in structure andeasy to obtain, easy mass production can be achieved, and the production cost is reduced. The whole device conveniently provides anti-collision protection for a bearing, and damage to the bearing dueto external force touch is avoided.

Description

technical field [0001] The invention relates to the technical field of wind power bearing protection, in particular to a novel wind power main bearing sealing structure. Background technique [0002] Wind power refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source. It has been used by people for a long time, mainly through windmills to pump water and grind flour. People are interested in how to use wind to generate electricity. Wind power bearings are special bearings that are used in harsh environments, require high maintenance costs, and require high service life. [0003] The existing wind power main bearings generally have retaining rings between the inner and outer rings for sealing and dustproof protection of the balls. The retaining ring needs to be processed together with the bearing, so that the size needs to be met accordingly, which increases the processing procedures and difficu...

AI Technical Summary

Problems solved by technology

[0004] The invention proposes a new sealing structure for wind power main bearings, which solves the problem that the retaining ring used for sealing on the existing wind power main bearings is inconvenient to quickly install and disassemble, and at the same time it is inconvenient for mass production and cannot reduce production costs.
